[Hexagon] Couple of fixes in optimize addressing mode

- Check if an operand is an immediate before calling getImm. Some operands
  that take constant values can actually have global symbols or other
  constant expressions.
- When a load-constant instruction can be folded into users, make sure to
  only delete it when all users have been successfully converted.
